WARNING

lPower Supply Ensure that the instrument’s supply voltage matches the voltage

of the power supply before turning ON the power.l Do Not Use in an Explosive Atmosphere Do not operate the instrument in locations with combustible

or explosive gases or steam. Operation in such environments constitutes an extreme safety hazard. Use of the instrument in environments with high concentrations of corrosive gas (H2S, SOX, etc.) for extended periods of time may cause a failure.

l Do Not Remove Internal Unit The internal unit should not be removed by anyone other than

YOKOGAWA's service personnel. There are dangerous high voltage parts inside. Additionally, do not replace the fuse by yourself.

l Damage to the Protective Construction Operation of the instrument in a manner not specified in the

operation guide may damage its protective construction.

CAUTION

This instrument is an EMC class A product. In a domestic environ-ment this product may cause radio interference in which case the user needs to take adequate measures.

3. How to Install

Installation LocationThe instrument shouldbe installed in indoor locationsmeeting the followingconditions:• Instrumented enclosure This instrument isdesignedtobemounted inan instrumentedenclosure.Mounttheinstrumentinalocationwhereitsterminalswillnotinadvertentlybetouched. Be sure to mount the instrument in an enclosure with a door.• Well ventilated locations Mounttheinstrumentinwellventilatedlocationstopreventtheinstrument’sinter-naltemperaturefromrising.

However,makesurethattheterminalportionsarenotexposedtowind.Exposureto wind may cause the temperature sensor accuracy to deteriorate.

5. How to Connect Wires

WARNING

• Wiring work must be carried out by a person with basic electrical knowledge and practical experience.

• Be sure to turn OFF the power supply to the controller before wiring to avoid an electric shock. Use a tester or similar device to ensure that no power is being supplied to a cable to be connected.

• For the wiring cable, the temperature rating is 75 °C or more.• As a safety measure, always install a circuit breaker (an IEC

60947-compatible product, 5 A, 100 V or 220 V AC) in an easily accessible location near the instrument. Moreover, provide indication that the switch is a device for turning off the power to the instrument.

• Install the power cable keeping a distance of more than 1 cm from other signal wires.

• The power cable is required to meet the IEC standards concerned or the requirements of the area in which the instrument is being installed.

• Wiring should be installed to conform to NEC (National Electrical Code: ANSI/NFPA-70) or the wiring construction standards in countries or regions where wiring will be installed.

• Since the insulation provided to each relay output terminal is Functional insulation, provide Reinforced insulation to the external of the device as necessary. (Refer to the drawing below.)

CAUTION

• When connecting two or more crimp-on terminal lugs to the single terminal block, bend the crimp-on terminal lugs before tightening the screw.

• Note that the wiring of two or more crimp-on terminal lugs to the single high-voltage terminal of the power supply and relay, etc. does not comply with the safety standard.

CAUTION

• Provide electricity from a single-phase power supply. If the power is noisy, install an isolation transformer on the primary side, and use a line filter on the secondary side. When measures against noise are taken, do not install the primary and secondary power cables close to each other.

• If there is a risk of external lightning surges, use a lightning arrester etc.

• For TC input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires.

• Since the control output relay has a life span (resistance load of 100,000 times), use the auxiliary relay to perform ON/OFF control.

• The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load.

• After completing the wiring, the terminal cover is recommended to use for the instrument.

• Do not use an unassigned terminal as the relay terminal. Do not use a 100-240 V AC power supply for the 24 V AC/DC

Use LL50ASoftware?

LL50A: Parameter setting software (sold separately)See the LL50A Parameter Setting Software User’s Manual (IM 05P05A01-01EN).Use LL50A with the controller turned on. (The dedicated cable must be connected. LL50A Light-loader adapter cannot be used.)The maintenance port is not isolated from the PV input terminal. Use the port only for maintenance purposes, such as for setting the controller parameters.

To set parameters through communication, you need to create a program on the host device side. For controller parameter information (registers, relays), see the following manuals.• For setup through RS485 serial

communication or Ethernet communication, see the UTAdvanced Series Communi-cation Interface User’s Manual (IM 05P07A01-01EN).

• For setup through an open network, see the UTAdvanced Series Communication Interface (Open Network) User’s Manual (IM 05P07A01-02EN).
